Robert Hooke

Robert Hooke Physics is the center of anything and everything in this universe. It is why we always come down after jumping up. It is why our Earth circles the Sun and the Moon circles our Earth. Behind all of these answers through equations stand many men and women who have been patient and determined enough to figure it all out. One of these fine beings would be a man by the name of Robert Hooke. Robert Hooke was born in July of 1635. He was the son of John Hooke, a churchman, who committed suicide when Hooke was but thirteen years old. This, along with his odd looks, affected him emotionally his entire life. But even being orphanized at such a young ago did not tamper with his love for science. From his work on clocks, to the publication of his Micrographia, gases, his inventions, his ideas on fossils, weather, springs, gravity, and light, Hooke has done many things in contributing to science and the world. Although he has done such great things, he went his entire life unrecognized for a lot of his work. Some Physicists even took his work, however this did not discourage him in continuing with his naturally born skill in science. Hooke was very famous in being a colleague of Isaac Newton. It is said that Newton “borrowed” many ideas from Hooke. Hooke had a very clear and accurate picture of gravity and planetary motion but everyone always thinks of Newton when something of that matter is brought up. Even though Hooke was unrecognized for a good many things, he was credited for a lot of inventions that have come to assist in science tremendously. Things such as: the universal joint, iris diaphragm, an early prototype of the respirator, an anchor escapement, balance spring, and he has devised an equation for elasticity which has come to be known as Hooke’s Law. Of course that is but a small list of things he has invented and contributed to the wonderful world of science. He also assisted Robert Boyle in studying the physics...

Introduction
Hooke's law states that force is directly proportional to the displacement of the spring that has been stretched or compressed from the equilibrium position. The force that takes place is referred to as a restoring force because it acts on an object to return it to a state of equilibrium. This is Hooke’s Law. It can be shown as:
F = -kx
In the first formula --->
F is the force of weight
k is the spring constant
x is the displacement
In this lab, we would have to know about the Simple Harmonic Motion (SHM).
T is the period
m is the mass
k is the spring constant
The characteristics of a wave are wavelength, amplitude, period and frequency. Wavelength is the length of the repeating wave shape. Amplitude is the maximum displacement or the greatest distance from the equilibrium point. Period is the time, in seconds, required to complete one cycle, and frequency is the number of cycles per second. Frequency is generally specified as Hertz (Hz) where 1 HZ = 1 cycle per second.
Purpose: The purpose of this lab is to manipulate and apply the concepts of Hooke’s law and determine the spring constant with the formula:
Procedure
1. Gather all your materials needed for the experiment.
2. Choose your surface.
3. Hang the spring on the assembled stand.
4. Attach the weight at the bottom of the spring.
5. Record the initial length of the spring.
6. Measure the length of the spring with the...

...V. Analysis and Conclusion
In this experiment we studied the elastic properties of the spring, the Hooke’s Law and the total work done on the spring when it is being stretch. Also, this experiment tackles the elasticity and deformation of a material that obeys the Hooke’s Law which states that “Within the elastic limit of a body, the deforming force is directly proportional to the elongation of the body.” Our experiment is to determine the force constant of the spring. The calculations used throughout this experiment were to determine the displacement, force, and the spring constant of the spring used. In order to find the displacement, which is the amount the spring has moved out of its equilibrium position, the average of the four trials for each force exerted is needed to be found. Once the averages are confirmed, the equilibrium position average is to be subtracted from the averages. In order to calculate the force, the equation F=ma is used where the m is the mass and a is the acceleration due to gravity. The mass would be the weights so, if to be finding the force of a 0.010kg weight, the force would be 0.010*9.8 which equals 0.098. Finally, to calculate the spring constant, the force is divided by the displacement. Using the results above, 0.098(force)/0.01225(displacement) = 8.000
Experiments are bound to have errors and uncertainties. First of all, human error is the always acknowledgeable in all experiments. While measuring the length of the...

...equilibrium position – the position of the free end when no force is applied. With the force applied to the spring, the spring now comes to rest in a new position. If we apply Newton’s Laws to the mass attached to the spring in the figure shown below, it is clear that the gravitational force of the mass on the spring must be balanced by a force from the spring in order for the spring-mass system to remain at rest. This force is called the spring force, Fs. The spring force is an example of a type of force referred to as a restoring force. This name comes from the fact that the spring force tries to restore the spring to its original un-stretched position where it is “comfortable” (the spring doesn’t like to be stretched nor compressed).
RobertHooke was the first to investigate the relationship between the applied force and the extension of the spring and deduced the law for elastic springs called Hooke’s Law in his honor. His law expresses a direct relationship between the applied force and the extension of the spring. Mathematically, Hooke’s law can be stated as Fa=k∆x. Fa stands for the applied force. The actual statement of Hooke’s law is Fs=-k∆x, where Fs is the spring force, the negative sign indicates the restoring nature of the spring force, and k is the constant of proportionality called the spring constant (some call it the force constant) that depend on the material and number of coils of the spring; k indicates the “stiffness” of...

...Born in Cork, Ireland, in the year 1627, Robert
Boyle was born into a very rich family. His
father, Richard Boyle, was the Earl of Cork.
Part of Boyle's success was because he
lived with one of the richest men of Ireland.
Richard Boyle, however, gained his money
through stealing. His mother died before he was
12.
Though he did well at his school initially, when
a new headmaster arrived, Boyle did poorly. His father
removed him from his school, and hired a tutor to
teach him philosophy, French and mathematics.
Though he did well in all of them, he excelled in math.
After some time, Boyle decided to joins the
"Invisible College" as refered to by Boyle. This is where
he discussed different scientific aspects. John Wilkins,
the leader of the Invisible College, offered Boyle to stay
at Oxford, where he could do his expirements as he
pleases.
His Father: Though he did not directly give any ideas and
inspiration, Boyle's success came from his private tutor
that would have been too expensive for anyone else other
than someone of his father's position.
Galileo: When he visited Italy, he learned about Galileo's
struggles with the Church. From this, he grew to respect
him and agree with Galileo's ideas about science's appli-
cation to life.
John Wilkins: Wilkins gave Boyle much of his education
which helped create his interest, and inspiration.
In 1662, Boyle did an expirement involving a
J Shaped tube,...

...Robert Boyle did not receive a traditional formal education like most people. His parents provided young Robert with the best education available in seventeenth century England. He attended Eton—the college founded by King Henry VI almost 200 years earlier—and also had private tutors. He was not more than 8 years old at the time. Robert was encouraged to continue his education in Europe. So Robert was sent off to mainland Europe, destined for school in Geneva.
After spending over three years at Eton, Robert traveled abroad with a French tutor. He had access to resources not available to students in England, and his knowledge broadened noticeably. He had a fondness for languages, mastering six, and found his interests also leaning greatly towards science.
In 1641, at 16 year-old in Italy, Robert had the privilege of meeting the aged and ailing astronomer Galileo, who paved the way to a better understanding of the universe. This meeting was something Robert cherished, and it provided a great impetus to the young man to try now to discover even more about God’s world.
Boyle returned to England in mid 1644 with a keen interest in science. His father had died the previous year and had left him the manor of Stalbridge in Dorset. From that time, he devoted his life to scientific research, and soon took a prominent place in the band of inquirers, known as the “Invisible...
